Green Bay sits at the mouth of the Fox River where it empties into the bay of Lake Michigan, and the river splits the city into east and west sides joined by a series of bridges. I-41 runs north and south along the west side, connecting the city to Appleton, Oshkosh and Milwaukee to the south and Marinette to the north. I-43 loops around the east side and crosses the river near its mouth on the Leo Frigo Bridge before heading south toward Manitowoc. WIS 172 crosses the south side between the airport and I-43, WIS 29 heads west toward Wausau and WIS 57 runs northeast toward Door County.
For a mobile mechanic, Green Bay is compact and easy to cross outside game days. The bridges across the Fox are the main pinch points, and the I-41 corridor through Ashwaubenon backs up at rush hour. Lombardi Avenue, Oneida Street and the streets around the stadium become gridlocked for hours on game days, and tailgating crowds fill every lot in the area. Most neighborhoods on both sides of the river have driveways and garages, which makes winter repairs more comfortable.
Austin Straubel International Airport sits southwest of the city, and its lots are a short drive from most neighborhoods. Green Bay Metro runs city buses. UW-Green Bay on the northeast shore of the bay, St. Norbert College in De Pere, Northeast Wisconsin Technical College and the hospitals on the east side draw daily traffic, and the paper mills along the Fox employ many shift workers. The bay and the river make good landmarks; share which side of the river you're on, since crossing at the wrong bridge adds time.
